Crossword Genius

Reveal second method (4)

Ross

I believe the answer is:

show

'reveal' is the definition.
(I know this)

'second method' is the wordplay.
'second' becomes 's' (common abbreviation).
'method' becomes 'how' (I've seen this in another clue).
's'+'how'='SHOW'

(Other definitions for show that I've seen before include "Entertainment - guide" , "Performance" , "plausible?" , "Demonstration" , "charade" .)

I've seen this clue in The Mirror and The Daily Express.
